How do we use Modal in two different pages?

When we use modal in ionic we have to declare the page/component in the nearest Module.ts

 async onCreateLead() {
    const modal = await this.mdlCntrl.create({
      component: LeadPage
    });
    return await modal.present();
  }

i have to use above lead component in two differece Pages(Modules) . when i try to use “LeadPage” in two diffecent modules error is raised :Type LeadPage is part of the declarations of 2 modules: ,
How do i solve this problem?

The modal should have a module declaration of its own

This module is then imported in the module of the calling pages
